Short answer: Water behind a dam escapes through a hole, turning a turbine and generating power.
Long answer: The easiest way to generate electricity, and the way that we pretty much always use (except with solar panels), is to spin a coil of wire between some magnets. (You could do it the other way and spin the magnets inside a coil, but magnets are heavy so normally we don't do it that way.) So that means we need a way to make this thing spin. For that, we use a turbine, which is basically a bunch of windmill-type blades stacked in front of one another that we can push water or air or steam through to get them to turn and make our coil spin. Now, the easiest way to get something to move is to drop it, i.e. to let gravity pull it for you. So in hydroelectric power, we build a dam to keep water from running downhill (i.e. increase its gravitational potential energy), then open up a gap in the dam and put a turbine there, so that when the water runs downhill, it turns the turbine, and we get beautiful clean electricity.
Hydroelectricity works by converting the energy from flowing or falling water into electricity. A dam is built on a river to create a reservoir, and water is released from the reservoir to flow through turbines, which spin a generator to produce electricity. The amount of electricity generated depends on the volume and height of the water flow.

What are the types of mechanical work?
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
How does input work and out put work affect the efficiency of a simple machine?
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
What formula relates work and power?
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
The work that the simple machine does is called the work?
The work that a simple machine does is called mechanical work. It refers to the amount of force applied over a distance to accomplish a task using the simple machine.
What is the formula to finding the work output of efficiency?
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
What is hydrolectricity?
electricity created by the flow of water turning a turbine
Why is energy added to the water cycle?
Energy is added when the Sun shines on the ocean, evaporating water from the surface that becomes water vapour and eventually forms clouds. This process gives the water a lot of potential energy due to its height. When the water falls as rain on the mountains and is collected by dams, it is used to drive water turbines and generators to produce hydrolectricity.
How did African slaves get education?
They got their education by secretly learning it if their master didn't allowed because it was illegal. Sometimes, their masters tought the slave even though it was against the law. By secretly learning it, they could learn it off another slave or steal a book and educate themselves.

What is the verb in you work late?

What is a work calendar?
A calendar at your work, for your work, that has your work schedule on it, etc.

What is the difference between work input and work output?
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
What is the differences between work input and work output?
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
